I want to update the SA_Last_MS field in the table T_PA_SubAwards with the Max value of the field PeriodNo in the subsidiary T_PA_Milestones table. The two tables are linked via the fields SA_RecNo and MS_SA_ID.
The task pictured runs but gives a value of 2 for all SubAwards with Milestones, and that is correct for most of them, although two SubAwards have 4 and 5 milestones, and these are erroneously set to 2 too.
Can someone tell me what is going on?
