How can TAPA item category be avoided during ATP check with RBA?

[Former Member]

Hi ,

We are planning to implement RBA in existing environment (SAP APO 5.0) .Our business concern that they don't want to implement RBA with item category "TAPA" which is returned during ATP check with RBA.

Is it possible to avoid item category "TAPA" SAP 5.0 during RBA ?

Thank You,

Anita

Hi Anita,

What is that with TAPA in sales order impacting i.e. what exactly is your business requirement, why they don't want TAPA in sales order, is the issue limited to aesthetics or some real business issues are being faced with this.

Explanation of the actual requirement will help in understanding your concern.

As per standard this is default, which can be changed to some other names off-course after looking at the impact it is making on other system functions and making necessary adjustments.

Hi Sourabh,

Thanks for reply. The requirement is that business don't want TAPA item category in Sales Orders any how. The following are the reasons-

1) In many scenarios this is undesirable as custom interfaces could be double reporting sales quantity.We asked them to make changes in reports & Z developmets but they are not ready for it.

There are hell lot of reports and Z where they can have similar kind of issue.

2) Because of TAPA, their sales orders will not be stated as complete.Which is also impacting in their process.

3) They don't want first line item with TAPA which can create confusion to business users and their customers.

As per my understanding one of the way to avoid this is write user exit, which before saving the sales order,copies TAN lines and delete TAPA line.

Is there any other way to avoid this (Although this is standard & default).

Thanks,

Anita

Hello Anita,

The requirement that you're looking for to suppress sub item is not possible in standard SAP. If you want to tweak the reports, you can easily identify the sub item and main items by using the referencing field UEPOS in VBAP table and adjust the reports accordingly. If the sub item is completely delivered, the main item is also set to complete and hence I don't see an issue there

Hi Anita,

As per your requirement suppressing the item category TAPA is not possible in standard rule based GATP as I have gone though the same issues of reporting ; various Z functionalities and main issue of pricing in sales order and their subsequent flow in further documents while implementing the RBA GATP.

If you try to modify the userexit to suppress the main item TAPA, then you need to think about consequences from the sales order processing point of view taking into consideration the pricing and subsequent delivery and billing process, The business requirement does not looks valid, Business must need to adjust their Z or BO reporting if like to enjoy the advantages of RBA GATP.

Hi Anita,

Firstly sorry for very long reply.

As per my understanding the concept is - The subitem(TAN- standard item) is relevant for ATP Check and price determination but the higher-level item(TAPA) is not. When order is created, the item category in the order is TAN.  The new order item 10 of type TAN is relevant for a rules-based ATP check in APO. When the ATP is executed and the result is written to a new RBA subitem (20). Now the subitem has the item type TAN and the item category usage APO1 or APO2 or something else based on the config. Hence subline item relevant for ATP and price determination now. The original item 10 is now the main item. Due to the results of the ATP check in APO, it has a new item category TAPA (meaning: sourcing main item)and the item category usage APO1 or something else as per config. It is therefore no longer relevant for ATP or for the price determination in SAP.

This how it looks
Item Material   Qty                               Item Cat   Item Usage
10 A  10   ( higher level item )             TAPA APOX
20 A 10   ( sub item )                           TAN   APOY

Note, Due to  item categories changes, The item 10 is no longer relevant for ATP and price determination. Instead, the sub item 20 is now relevant for ATP and price determination.

The importance of Item Usage field in item category determination (Tcode: VOV4 ) tells if you use your main item category with same usage then some item category gets determined automatically in the sales order. In determining a Item Category system takes in to account Sales Document Type, Item Category Group, Higher level Item Category and Item Usage.

Item category is linked to item group and order type in SPRO settings.
Item usage and higher level item category are linked in the item category determination in SPRO.

IMG Path: Sales and Distribution > Sales > Sales Documents > Sales Document Item >

Also try Tcode VOV7 - Define Item Categories.

Item usage                                                                               
The item usage indicator controls the system reaction when you process a sales document item in a certain context.                                                                     
Use                                                                               
This indicator can be used for determination of item categories, where you can use it to control which other item categories are to be found in a certain environment (text items and packing items, for example). It can also control which items are to be billed in a service quotation or the corresponding sales order and which are only there for statistical reasons.

See more at:  SAP Note Note 505086 - Alternative item category during rules-based ATP.               

Although above explanation doesn't really answer the question, but it will give you some insight on item category determination in SAP.  I suggest you to investigate on this topic - Item usage/Item Category determination. Hopefully you will find some option/workaround soon.

Besides as you know, this is how standard SAP works with RBA, many of the companies are using RBA and it is helping them meet their business requirements. Having a TAPA does not add into any complications and because TAPA line is not relevant for ATP check or Price Determination in SAP. In fact it helps you know about Original order qty and other details. It will be interesting to know reason behind Business Concern on TAPA line. Please think on this as well.

Please do post if you able to figure out an option.

Good Luck...!

Thank you

Please see the answer in thread with required BADI enhancement, config in APO and ECC.

Results will show you "plant has been changed on main item " and no TAPA line appears.
