Tables not populated during data upgrade.

I have 2 cases of not populated tables after data upgrade from AX4 to AX 2012.

One is the DirPartyTable, that should have a record for every customer. In AX4, the table was created and populated. But the BulkCopy to AX 2012 R3 was not done.

¿Is there any script I can use to load it?

Also I have a custom table, that has been created in AX 2012 R3 after de code upgrade, but the data hasn’t been loaded. I haven’t seen anything in the Data Upgrade scripts whitepaper that clearly states how to do a BulkCopy of a custom table. Please can someone point me in the right direction to correctly load this 2 tables?
