EXIT_SAPLV50E_001 User Exit is not working for multiple plants case

Hi,

I have to update foreign trade data in Invoice during invoice creation using VF11. For that, I have written code in EXIT_SAPLV50E_001 and updated segal value. This functionality is working fine, if I have a single plant in an invoice. But customer has scenario where they can have multipl plants in an invoice.

For multiple plants in an invoice, this EXIT_SAPLV50E_001 is not called. 😔

I am unable to find another better place where in I could place my code. Please help. Remember, case in multiple plants.

Will be rewarded.

Regards

Arpit
