Regarding proof of deliver quantity field
In customer master transaction POD of time interface (field PODTG) is linked to the proof of delivery outbound transaction (T code VLPOD) of POD quantity field (PODMG), when ever you are changing qty diff sales unit, Reason fields (LFIMG_DIFF, GRUND).
For example, in transaction XD01, if we enter PODTG value 1 day, based on this information (PODTG value 1 day) pod quantity value will be updated automatically as delivered quantity in VLPOD transaction. In case of manual entry, qty diff sales unit, Reason fields (LFIMG_DIFF, GRUND), that particular quantity will be deducted from delivered quantity and it will be stored in pod quantity (PODMG).
Now my requirement is, In case of pod quantity (PODMG).value doesnt updated with in one day (PODTG field value) , we should send an email to manager.. Is there any exits available for this functionality otherwise is there any particular procedure available for this.
