Export Indicator in Intracompany STO transfers

Hi,

We are trying to do a local transfer of a material within same company code.

The foreign trade data gets into the delivery,-- mode of transport is coming and this is setting the export indicator in the delivery which is getting copied to the proforma invoice.

Due to this the printing logic is thinking it as export scenario whereas its local sale.

Can anyone let me know, how this data comes into delivery or the PO?

I have checked the PO, but this data is not in PO, but comes up in the delivery

Any help is greatly appreciated

Thanks
