## Function Syntax

```plaintext theme={null}
long SCC_SetAppProtocolData(long ProtocolIndex, long Index, long Value);
```

## Description

Overwrite the fields **VersionNumberMajor**, **VersionNumberMinor**, **SchemaID** or **Priority** after a SupportedAppProtocolReq message has been created using [SCC\_CreateSupportedAppProtocolReq](CAPLfunctionSCCCreateSupportedAppProtocolReq.md).

## Parameters

* **ProtocolIndex**: The index of the AppProtocol entry to be modified, starting at 0 (zero). An error will be returned if the index is invalid.
* **Index**: The index of the field in the selected AppProtocol. The following indices are defined:
  * 1: VersionNumberMajor
  * 2: VersionNumberMinor
  * 3: SchemaID
  * 4: Priority
  * Any other index will cause an error to be returned.
* **Value**: The new value for the selected field.

## Return Values

* `0`: error
* `1`: success

## Example

```plaintext theme={null}
// create a SupportedAppProtocolReq message using test configuration with ID="2"
SCC_CreateSupportedAppProtocolReq(2);
// set the VersonNumberMinor of the first AppProtocol element to 1
SCC_SetAppProtocolData(0, 2, 1);
// send the modified message
SCC_SendPreparedMessage();
```
