I read that the Table filter datatype are meant for internal use by navision but here is one example where i was able to you it very effectively.
This was when we were building a promotions module where in it occurred that the items and customers eligible for the promotions to work should be accepted as filters so we used table filters fields for the same.
Table filter fields cannot be directly used in navision but there are indirect ways to use it as shown below :
Variable Used
-------------------------------------------------------------------------------------------------
ItemForm = Form ( Item List )
ItemRecord = Record (Item)
TableFilter = Variant
-------------------------------------------------------------------------------------------------
Item Filter - OnAssistEdit()
-------------------------------------------------------------------------------------------------
CLEAR(ItemForm);
ApplyItemFilter(ItemRecord);
ItemForm.SETTABLEVIEW(ItemRecord);
ItemForm.LOOKUPMODE := TRUE;
IF ItemForm.RUNMODAL = ACTION::LookupOK THEN BEGIN
ItemForm.CopyFilters(ItemRecord);
IF ItemRecord.GETFILTERS() = '' THEN BEGIN
TableFilter := '';
EVALUATE("Customer Filter", TableFilter);
END ELSE BEGIN
TableFilter := ItemRecord.TABLENAME + ':' + CONVERTSTR(ItemRecord.GETFILTERS
,':'
,'=');
EVALUATE("Item Filter", FORMAT(TableFilter));
END;
END;
