Hello Mr. Jogeswara,
Thanks for providing the guidelines.
As per your suggestion I will try and get back to you.Just wanted little more clarification on below mentioned point from you.
You can maintain the External station codes in the Catalog1 (valuation code in any one of the measuring points preferably in the Diesel Qty) so that while creating the document you can select the external gas station.(Ignore if not feasible).
I didnt get what you are trying to say to maintain catalog1 for external gas station and valuation code in any one measuring points.
Regards.
Swapnil
