EWM : Adding a field to the HU Field catalog

Introduction

Adding a new field to the Handling unit field catalog in customizing is just not enough to make it work. Here are the details , what all has to be done.

Customizing

At the following path, new field has to be added.

Customizing path

Added field as follows:

Added Field

Maintain condition records

In the transaction /SCWM/PRHU6 , the newly added field should now be available in order to maintain the condition records.

Condition records

While attempting to generate the action through /SCWM/VASEXEC , would still not create any action in SPPFP. The reason is, newly added field has to be filled with the value .

Badi Implementation

Badi /SCWM/ES_PRNT_CCAT , method CHANGE has to be implemented , in order to provide value to the newly added field.  Here is the code sample from this scenario.

    DATA: lo_context         TYPE REF TO /scwm/cl_hu_cxt_ppf.
    DATA: lo_ao_hu           TYPE REF TO /scwm/cl_hu_ppf.
    DATA: lv_huident         TYPE /scwm/de_huident.
    DATA: lv_ttype           TYPE ppfdtt.
    DATA : lv_vsbed          TYPE /scwm/vsbed.
    FIELD-SYMBOLS : <request> TYPE /sapcnd/det_request .
    FIELD-SYMBOLS : <item_attr> TYPE /sapcnd/det_attrib_value .
    DATA: ls_item_attr TYPE /sapcnd/det_attrib_value .
    DATA:  ls_attribute       TYPE /sapcnd/det_attrib_value.
    DATA:      lt_huref             TYPE /scwm/tt_huref_int.
    DATA: ls_item TYPE /scdl/db_proci_o.
    DATA : ls_vbfa TYPE vbfa,
           ls_likp TYPE likp.
    DATA : lf_vsbed TYPE vsbed.

    DATA: lt_ordim_int TYPE /scwm/tt_ltap_vb,
          ls_starea    TYPE /scwm/tstarea.

    ENDIF.

After Implementing this Badi, action should be generated .

Conclusion

There may be some additional steps needed depending on the scenario, the above given steps were sufficient to make shipping conditions work.
