Hi,
First option: In some dimension SOMEDIM you can create 2 properties: PLAN and PLANMONTH. For some dummy member you can maintain the mentioned properties like:
SOMEMEMBER
PLAN: JUNFCST
PLANMONTH: 2012.OCT
Then in all scripts you can get this properties like:
*SELECT(%PLANCONST%,"[PLAN]",SOMEDIM,"[ID]='SOMEMEMBER'")
*SELECT(%PLANMONTHCONST%,"[PLANMONTH]",SOMEDIM,"[ID]='SOMEMEMBER'")
Second option: use BADI to get and set global variables...
