Shopping cart creation category dropdown selecting the most used category

Question

Hi SRM gurus,
While creating a shopping cart one of our most used category gets selected by default before we start doing anything.
Everytime we have to change the category.
Is there a way that will become blank and we can select from the dropdown or the find list.
Kindly suggest.
We are using SRM component version 4.0, SRM server 5.0, our patch level 0008.
Thx. & reg.,
Sridhar.

Hi
<b>Yes.. This was happening with us when we used SRM 4.0 version.
We have used an  BADI Implementation to resolve this issue.</b>
<u>The BADI name is <b> BBP_F4_READ_ON_EXIT </b></u>
For Product category -> Product category (attr. WGR, PRCAT)  GET_CATEGORY Method, you need to go ahead.
<u>Read the documenation of this BADI and you will get the problem resolved after implementing the same.</u>
Here is the documentation
BBP_F4_READ_ON_EXIT
Short Text
Restrict the Display in Input Helps and Search Helps
You can use the Business Add-In (BAdI) BBP_F4_READ_ON_EXIT to restrict (or augment) the list of values and favorites that are output in the input and search helps. You can only process data elements for which input helps exist on HTML templates. The following three BAdIs are also available:
BBP_F4_READ_ON_ENTRY
Use this BAdI if you do not just want to restrict the favorites and values list but also want to select this yourself.
BBP_F4_MEM_UPDATE
BBP_F4_SAVE_DB
The following three modules are used to process the values per data element:
BBP_GET_<data element>_F4
Supplies a list of all values and user-specific favorites. You can influence how this module works using BAdI BBP_F4_READ_ON_ENTRY and BBP_F4_READ_ON_EXIT.
BBP_UPD_<data element>_FAV
Updates the favorites in internal function group storage. You can influence how this module works using BAdI BBP_F4_MEM_UPDATE.
BBP_SET_<data element>_FAV
Writes the current favorites to the database. You can influence how this module behaves using BAdI BBP_F4_SAV_DB.
Use
Only implement this BAdI and only program the appropriate method if you want to restrict or augment the value set of standard selection.
If you determine favorites using a BAdI, the standard modules do not process the favorites further. Warning: If, deviating from standard selection, you determine the list of favorites yourself using a BAdI, you have to temporarily store the favorites in the methods of the BAdIs and carry out final saving to the database yourself.
Standard settings
If data is added via the methods, no check of this data occurs. The check has to occur in the methods themselves.
The interfaces of the methods of the BAdI are (almost) always the same:
IV_LANGUAGE
Language for determination of the texts
IV_USER
User for which the values are requested
ET_<data element>_LIST
The list of valid values changed by you
EV_X_FAV_PROCESSED
Use "X" to stipulate that you have filled the favorites list. Only present if favorites table exists for relevant data element.
ET_<data element>_FAVOURITES
Changed favorites list for user IV_USER. Only exists if favorites table exists for relevant data element.
The methods have to fill the structures of the transfer tables completely. Incompletely filled structures can cause followup errors and unforseen consequences.
Activities
Reading of value lists and favorites using function module BBP_GET_<data element>_F4 occurs as follows:
1. First the BAdI BBP_F4_READ_ON_ENTRY is called. It is possible to fill the input list (and favorites) with default values.
a) In the case of default values, exactly these values are returned to the initiator. No further processing or check occurs and the module is exited.
b) If no default values exist, the standard selection is carried out.
2. Before the values are transferred externally you can restrict or augment the number of hits using the BAdI BBP_F4_READ_ON_EXIT. You can therefore delete entries from or add entries to the input list or favorites list.
3. BAdI BBP_F4_READ_ON_EXIT provides an individual method for each data element for which an input help and/or favorites table exists. These are listed below.
If you use this method, you need to indicate processing using the parameter EV_X_LIST_PROCESSED or EV_X_FAV_PROCESSED. Otherwise the selection is lost.
