# BC sets

## Prerequisites

The BC sets required to correctly configure PreBilt in the first instance are provided by TCT. Access to transactions *SCPR3* and *SCPR20* in the Development environment is necessary. You should identify the package for saving the BC sets per your internal processes; otherwise, use package Z001.

The BC sets provided by TCT are created in a Unicode system. If the target SAP system is not Unicode, the [activation](#activate-a-bc-set) below will slightly differ.  To find out whether your system us Unicode or not, in SAP go to `System -> Status` and look for the 'Unicode System' field which will display either 'Yes' or 'No'.

## Importing a BC set

{% hint style="info" %}
**Note**

This section should be completed in the normal customising client and saved as a local object.
{% endhint %}

In transaction *SCPR3* click the 'Upload BC Set' icon and select the BC set to be uploaded in the dialog box.

When the BC set has been loaded, select the Save icon to save the BC set.

## Activate a BC set

In transaction *SCPR20*, enter the name of the BC Set and select the ‘Activate BC Set’ icon.

On the following pop-up, if the SAP system is a Unicode system then leave the Activation Mode as ‘Default Mode’. If it isn’t Unicode, then change the Activation Mode to ‘Expert Mode’. This will ensure that all the sequence numbers of the configuration fields are loaded as determined in the BC set.

Press 'Enter'.

An amber warning message may be seen, saying 'Activation ended in warning'.  If this is the case, click the 'Activation Log' icon at the top of the screen. If only amber and green icons are displayed, the transaction will have created successfully. (If successful, you will also see the transaction has appeared in transaction */TCTM/WM\_CFG*).

## Deleting a BC set

{% hint style="info" %}
**Note**

If this action is being completed during the process to delete a transaction, all AMD should be deleted first, followed by the transaction from */TCTM/WM\_CFG*, and then the BC set.
{% endhint %}

Go to transaction *SCPR3* and load the BC sets that were previously created by selecting the ‘User BC Sets’ option under the ‘New BC Set Selection’ icon.

Double click on the BC set you want to delete from the left-hand panel and press the 'Delete' icon or right click on the BC set and select 'Delete BC Set.

<figure><img src="/files/MTcJz6PrXfi8jZRm6wri" alt=""><figcaption></figcaption></figure>

Confirm the deletion by clicking 'Yes' on the pop-up and a success message will be displayed at the bottom of the screen.
