I Have Imported data from implementation

I Inserted data for table Purchase Line (table 39)

But field “VAT Prod. Posting Group” didn’t validated

so I musti validate it one by one, and then I tried to customized code to validate all records in purchase line for field “VAT Prod. Posting Group”

I Made like this

GET(“Document Type”,“Document No.”,“Line No.”);  
VALIDATE(“VAT Prod. Posting Group”,‘PPN’);

but it didn’t work… could anyone help me?
