Oracle Essbase 9 Implementation Guide- P39 ppsx

Chapter 5 [ 175 ] The command above enables four threads to run in parallel. This means that upto four threads can be used by the system to calculate the data instead of the default one thread. • SET FRMLBOTTOMUP ON/OFF: This command enables you to do bottom-up calculation on the formulas. The command can help speed up the processing of complex formulas on Sparse Dimensions when the associations and dependencies are straight forward. When there are a lot of range type functions used, there may be inconsistent results achieved. SET FRMLBOTTOMUP ON; SET FRMLBOTTOMUP OFF; • DATACOPY membername1 to membername2: This command copies data from one member to another member. DATACOPY "TOTAL REVENUE" to "BILLED REVENUE"; This example above will copy the values in TOTAL REVENUE to BILLED REVENUE across all levels. DATACOPY "TOTAL REVENUE"->@LEVMBRS("Calendar Periods", 3) to "BILLED REVENUE"->@LEVMBRS("Calendar Periods", 0); This example above will copy TOTAL REVENUE from the YEARS level to BILLED REVENUE at the month level. In a database calculation script, member names which have a space in them must be in double quotes. If there is no space in a member name, there is no need to have a double quote. It is not a bad idea to always wrap member names in double quotes, whether they contain spaces or not. This makes them easily identiable when reading a calc script. • CLEARBLOCK ALL/UPPER/NONINPUT/DYNAMIC/EMPTY: This command clears the blocks and sets "#missing" in the blocks. You need to clear blocks before data refreshes to clear off all of the old data. Remember, this is not entirely removing the blocks, these blocks still exist and when you do a data load it will be a little slower. If a block had no data already, meaning it is already #missing, it will be removed. ° ALL: Clears and sets "#missing" to all data blocks. ° UPPER: Clears and sets "#missing" to all of the consolidated level blocks. ° NON INPUT: Clears and sets "#missing" to all of the non-input members, the members to which data is not directly loaded.

Examples: CLEARBLOCK ALL; CLEARBLOCK UPPER; • CLEARDATA MemberName: Removes all of the data for the member name specied, replacing it with "#missing". The "#missing" symbol is Essbase speak for null values. Example: CLEARDATA "TOTAL REVENUE"; The functions discussed above are just some of the more widely used calculation script functions available to you. We will discuss more functions in the coming chapters. Conditionals In the Essbase database calculation script, like most other programming languages, you can test data situations with conditional statements. Without a doubt, the IF and ENDIF statements are the most common. IF/ENDIF Ah yes, the IF and ENDIF commands, the partners to the FIX and ENDFIX commands. As stated earlier in this chapter, these tools have been provided to allow you to write high performing and efcient calculation scripts and to precisely calculate your data without stomping on other data. If the FIX and ENDFIX commands are the gate keeper of the data, the IF and ENDIF commands are the ushers directing you (your data) to the correct seat. Just like the IF and ENDIF commands in any programming language, the IF and ENDIF commands you use in Essbase for calculating, perform conditional checking or testing of the data to help decide if or how it gets calculated.

Well, the opposite is recommended for the IF and ENDIF commands. Because the IF statement needs to test every occurrence of the data brought to it, it is best to use the IF and ENDIF commands against a Dense Dimension because there will be fewer cells of data that need to be tested since the original subset of data was pulled in as a Sparse Dimension. For example: FIX(Sparse Dimension) IF(Dense Dimension) Any Calculation Function; ENDIF ENDFIX Again, while this is not always possible, it is a good idea to follow this recommendation whenever possible. Just like the FIX and ENDFIX commands, the IF and ENDIF commands can be nested. We have never been able to determine if there is a limit, but we have also never hit a limit when coding either. For every IF statement, there must be a matching ENDIF statement. When using ELSE or ELSEIF, you will still need one ENDIF for every IF statement. For example: IF(Conditional Argument) Any Calculation Function; ENDIF Or this: IF(Conditional Argument) IF(Conditional Argument) Any Calculation Function; ELSEIF(Conditional Argument) Any Calculation Function; ELSE Any Calculation Function; ENDIF ENDIF Also, like the FIX and ENDFIX commands, the IF and ENDIF command statements do not need to be terminated with a semi-colon. Only the actionable calculation function statements need to be terminated by a semi-colon.

Much like the FIX command, the IF command accepts a comma separated list of conditional arguments, of which a full compliment is included in Essbase. Always remember with IF and ENDIF, you want to Fix on Sparse and IF on Dense. Boolean As you know, Boolean tests are used to check for either a true or false condition. In an Essbase calc script, you can make good use of the Boolean test functions. Some of the more widely used Boolean functions are @ISUDA, @ISMBR, @ISLEV, @ISGEN, @ISPARENT, @ISCHILD, and many more. Some of the most widely used Boolean functions are discussed here: • @ISMBR: This function is used to test if the current member being calculated is a member specied by the parameter(s) entered into the function. Syntax: @ISMBR (membername, rangelist, mbrlist) ° membername—a single member name ° rangelist—a range of members returned by a member function ° mbrlist—a comma separated list of members Example: @ISMBR("DETROIT")—returns true if the current member is DETROIT. • @ISLEV: Returns true if the current member being calculated is in the same level as the member specied in the @ISLEV parameter. Syntax : @ISLEV(dimname, levelname, level number) Example: @ISLEV("TOTAL CUSTOMER",0)—returns true if the current member is in the zero level in the database outline. • @ISCHILD(mbrname): Returns true if the current member is child of the member specied in the @ISCHILD parameter. Syntax: @ISCHILD(mbrname) This material is copyright and is licensed for the sole use by Paul Corcorran on 5th July 2009 8601 ave. p #1, , lubbock, , 79423 Download at Boykma.Com Chapter 5 [ 179 ] Example: @ISCHILD("DETROIT")—returns true for all members that are children of the DETROIT member. These are just a few of the many Boolean functions that Essbase has provided to you to allow for the increased performance of customized database calculations. You should now have a good understanding on their use and the parameters required to make them perform as designed. Relationship functions As you know, an Essbase cube is lot like a family. In fact, this is a family that has a lot of relationships. The relationship functions are used to fetch data for the current member position from a different member's position. The most widely used relationship functions are @PARENTVAL and @ANCESTVAL. • @PARENTVAL (dimension, membername): This function returns the value of the parent of the current member being calculated for the listed member. Example: @PARENTVAL("TOTAL VEHICLE","TOTAL SALES"): This returns the TOTAL SALES for the parent of the current member. This is the product structure of our Esscar Database: If the current product member being calculated is "2 DOOR SEDAN", then the output of this: @PARENTVAL ("TOTAL VEHICLE","TOTAL SALES") is TOTAL SALES for the CARS outline member which is the parent of "2 DOOR SEDAN". • @ANCESTVAL (dimension, genlevNum, [membername]): This function returns the value of the parents, grandparents, great grandparents using either the generation or level reference from the current member selected.
