How to prepare TSD ?

[Former Member]

Hi all,

How to prepare a technical specification document for example say, open purchase order  in MM module? What does a  TSD basically contain? I will give you the scenario, please let me know what all should be mentioned in a TSD doc. Do I need to include what all functions I will be working on? I am new to ABAP , please guide me. Thanks in advance.

Business Scenario: 

Report should display a list of open purchase orders when the PO quantity is greater than the total goods receipt quantity.

The following is the input:

Table/Field Name	Field	Optional /Required	Remarks
EKKO-EBELN	PO #	O
EKKO-EBDAT	Document date	R
EKKO-BSART	Purchasing doc type	O
EKKO-BSTYP	Purchasing doc category	O
EKKO-EKGRP	Purchasing group	O
EKKO- WERKS	Plant	O
EKPO- EBELP	Item# in PO	O
EKPO- MATKL	Material group	O
EKKO-BUKRS	Company Code	O
EKKO-EKORG	Purchase Organization	O
EKPO-MATNR	Material #	O

Processing Logic:

Pull the list of PO’s with the above selection criteria based on below logic.

Check the entry exist in EKBE table and when EKBE-VGABE = 1.

If entry does not exist in EKBE, for those PO’s Goods Receipt is not done. So list all those PO’s in the output with the details given in the output format. For these PO’s Total GR Quantity in the output will be 0 and open PO quantity will be same as PO quantity.

For those PO’s where entries are available in EKBE, then pull the below material document data for PO line items.

EKBE-EBELN----- PO Number

EKBE-EBELP------ PO Line Item Number

EKBE-BELNR------Material Document Number

EKBE-MENGE-----Quantity

Sum up the GR quantities (EKBE-MENGE) for the material documents at PO line item level to derive “ Total GR quantity” and list the PO’s in the output where the “PO quantity” is greater than the “Total GR quantity”. Open PO quantity for this case will be “PO Quantity - Total GR quantity”.

Output Format:

PO No	Line Item Number	PO Date	PO Quantity	Total GR Quantity	Open PO Quantity
EKKO-EBELN	EKPO- EBELP	EKKO-EBDAT	EKPO-MENGE	As per the logic given above	As per the logic given above

heard of flow chart or pseudo code, base your tsd on that.

from start(selection screen) to end(report output) what all will you do, you need to document that in a brief manner.
