When to use *XDIM_MEMBERSET MEASURES=PERIODIC in the script

Hi experts,

I am not sure on when to use this stmt in the script logic

*XDIM_MEMBERSET MEASURES=PERIODIC

We have created consolidation application as periodic. (We are on NW7.5 SP06)

-

//Roll current month P&L CTA adjustment to RE

*XDIM_MEMBERSET MEASURES=PERIODIC

*WHEN KT_A_ACCOUNT.RATETYPE

*IS "AVG"

*WHEN KT_TRANSTYPE

*IS "F_CTA_C_PL"

*WHEN KT_GROUPS

*IS "GC"

REC(EXPRESSION=(%VALUE%)(-1),KT_A_ACCOUNT=900000,KT_TRANSTYPE=F_CTA_C_PL,KT_GROUPS=GC,KT_A_DATASRC=CURR_TRANS)

*REC(EXPRESSION=(%VALUE%),KT_A_ACCOUNT=311000,KT_TRANSTYPE=F_CTA_C_PL,KT_GROUPS=GC,KT_A_DATASRC=CURR_TRANS)

*ENDWHEN

*ENDWHEN

*ENDWHEN

*COMMIT

If I comment the stmnt *XDIM_MEMBERSET MEASURES=PERIODIC , in the above script, the calculation takes into account the sign convention based on the ACC_TYPE and the values come incorrect.

Thanks
