i've a requirement to change the ALV layout of t-code LI20.
After debug the program, found out that its calling report RLLI1400 to generate the ALV.
Since there is no enhancement point available in RLLI1400 to fulfil user's requirement, i've created a Zprogram (Wrapper of RLLI1400) for that.
requirement in LI20 :
The inventory doc was change from parameter to select-option (hence, we could have multiple inventory doc retrieve).
requirement in RLLI1400 :
Group by the inventory doc, then storage bin, then only material.
Existing RLLI1400 is display by Storage bin.
My question is how can we make use of REUSE_ALV_HIERSEQ_LIST_DISPLAY to display by Inventory Doc, then only storage bin ?
Thanks in advance for all the advise.
