The Boolean condition in rollup substitution (view V_T892U) is replaced by a rule for performance reasons.
The old conditions are automatically converted to rules using XPRAs RGXU892U as follows:
'XA' + T892U-SUBACT + T892U-SEQNR
Example: condition TEST 001 in V_T892U automatically becomes rule XATEST001.
You can define new rules using transaktion GCVZ and then enter them directly in the rollup substitution.
