Script Logic Posts to Non-existent Member

Hi,

We have an issue with a piece of script logic which seems to post to a member which doesn't actually exist.

This is the code which posts the data:

//Copies KG_FACTOR for WIP from the Product dimension to the WIP dimension

*XDIM_MEMBERSET ACCLABOUR = KG_FACTOR

*WHEN PRODUCT.PROD_TYPE

*IS "WIP"

*REC(FACTOR=1, WIP=PRODUCT.SPS_SORTKEY, PRODUCT="NOPRODUCT")

*ENDWHEN

*COMMIT

The property SPS_SORTKEY sometimes contains a member which does not exist in the WIP dimension but the datamanager package doesn't seem to check this.

We are currently on BPC v.7 but shortly upgrading to 7.5. Is this something which would be resolved in 7.5 or do we need to make a chage to this script logic to prevent this from happening?

Thanks,

Jamie
