Dears, 

We ‘d like to have EDI for purchase orders with our supplier (both ORDERS and ORDRSP) but

in IFS lines are identified with Line_no and Rel_no and our supplier doesn’t manage Rel_no

What can we do?

Thanks in advance

Example - case 1 

In ORDERS IFS sends  :

Line = 1 Rel_no = 1

Line = 1 Rel_no = 2

The supplier receives

Line 1 (with data coming from the last one (relNo 2) and the 1st line is lost)

And in ORDRSP the Supplier replies 

Line = 1 Rel_no = 1  (only with data related to the second line)

Example - case 2

In ORDERS IFS sends  :

Line = 1 Rel_no = 1

Line = 1 Rel_no = 2

The supplier receives

Line 1 

Line 2  (with problems in case there is from IFS line_no 2 rel_no=1)

And in ORDRSP the Supplier replies 

Line = 1 Rel_no = 1

Line = 2 Rel_no = 1
