This Entry Already exists in table (Message: 131-183)

Question

Hia All,
I have a very serious problem that's I have been unable to solve on my own.
I have a User defined form that is linked to a User defined Object. The Object consists of a Master data and a Master Data Lines table.
I am able to add a record without any problem, but I attempt to update an existing record I get the following error: "This entry already exists in the following tables..."
Strangely, this only happens when I add iditional records to the Lines table, and not when existing data is altered.
Please help me.

Hi Ben, yes I was able to solve the problem.
It seems that when you add additional rows to your lines table, you have to manually add the records to the DBDatasource on the before action. i.e. Catch the Item Pressed before action on item 1 (OK button), and manually insert the additional lines into the DBDatasource as displayed below.
e.g.
i = oForm.DataSources.DBDataSources.Item(1).Size
oForm.DataSources.DBDataSources.Item(1).InsertRecord(i)
oForm.DataSources.DBDataSources.Item(1).Offset = oForm.DataSources.DBDataSources.Item(1).Size - 1
oForm.DataSources.DBDataSources.Item(1).SetValue("U_ItemCode", i, Code)
This code will typically reside insode a loop seeing as you will loop through your matrix/grid rows and add the additional lines.
This sorted out the problem for me, I hope it hepls you.
