Wrong Confirmations giving error in DP90
I have done some labour hour confirmations confirmations againt the service order. Out of all these confirmations some time confirmations are with wrong activity type. These wrong activity types are not for material determination in DP90. Then we reversed / cancelled the confirmations with wrong activity type. But still these confirmations are giving error of material determination in DP90. Pl. suggest how can I get rid of this material determination error in DP90 for those wrong and cancelled confirmations.
Finally we have done the enhancement in DP90 and ignored the cancelled CO posting from the source of DP90. Now works fine.
Thanks to Pete for his suggestion.
