Hi,
Please check the following:
1. In MIRO - "Goods/services + planned Delivery cost" or "Planned Delivery Cost" option is selected with Invoice.
2. If the condition type FRB1 is not appearing in MIRO when checked as explained in step 1, then go to M/06 and check the condition category for the condition type FRb1. It should be B - Delivery cost.
3. If the condition type is appearing in MIRO without quantity and value, check whether the GR has been done for the PO. The quantity and value will be automatically in MIRO only if the GR is done. It is standard behavior. If GR is not done, you have to enter the quantity and value manually.
Revert back if its not solved or the issue is different.
Regards,
AKPT
