# Child application deployment from parent application

Hi [@Ben](https://forum.algorand.co/u/ben),

This is definitely one of the problems I had. Moreover, I forgot to set also the global and local schema. With this solution, encoding the abi.String, now the transaction is executed correctly.

```python
InnerTxnBuilder.Begin(),
InnerTxnBuilder.SetFields(
{
    TxnField.type_enum: TxnType.…
}
)
```
