Use EXIT_/SAPAPO/SAPLCIF_PU_001 for changing PO data

Question

We have in some situations the need to change the delivery date (EKET_EINDT) of a purchase order in the CIF interface, and have been looking at exit EXIT_/SAPAPO/SAPLCIF_PU_001 to do this.
However the exit is not documented particularly good, and we are struggleing to find which fields to change. Do anyone have some detailed documentation of this exit, or do someone have an idea of what we want to do, can be done in this exit? Are there alternative exits we could look at or perhaps a BadI?
Thanks for any input.
Regards

Hi,
    You have to check the exact date field in Debugger because there are couple of date fields in the given User Exit.I would suggest to use the CIF user exit in ECC CIFPUR01-Enhancement for Transferring Customer-Specific PO Fields in which you can restrict the functionality on basis of CIFOBJTYPE = 2(Purchase Order).
In the field TMSTMP, check what value is coming in User Exit and if it is the correct one then you can change it here.
If further information required please let me know.
