Remove all tge code from OnPreReport. It is not working, you cannot get information from, or manipulate, the dataitems there.
Move the periodtext code line to onpredataitem delivery challan line. It will get the postingdatefilter in a text string. Probably shown somewhere on the report.

Set all the filters onpredataitem, preferrably only for the REC that populates that dataitem.

To be short.. this report is a mess
