Need yr expertise. We have a scenario where after PGI we will send an IDOC to 3PL and they would send an external no. back to SAP via IDOC. We need to store this no. in delivery no. Im thinking of using LIKP-LIFEX field.
How do we update the external no. into LIKP-LIFEX after PGI as the field is grey off? Is there a way that we update those field although it is grey off.
