Account Based Calculculation Limit by Entity Dimension

Hi Experts,

I’m building a series of (reclassification) postings that are limited to specific Entities.  So entity 1000 there will be posting to from account 1234 to 1235 and for entity 1200 there will be a posting from 1234 to 1236.

I can use the Script logic but thought maybe the Account Based Calculation (ABC) table SPRUCALCACCOUNT could be a tool. 

We did this successfully in the NetWeaver version and limited the activation of the ABC logic by entity by a preceding script logic limit to activate the posting – there you can define multiple ABC tables.

Here in MS, I thought of doing something similar and limit by Transformation Group.

Is this possible?

If so, does anyone know the syntax e.g.

WHEN TRANSFORMATION GROUP IS CALC1010?

I would also need to write script to clear the postings before proceedings? Or does it overwrite the prior calculation  automatically?

Thanks in advance.

Regards,

Eyal
