This component offers the advantage of the
dynamic schema feature. This allows you to retrieve unknown columns from source
files or to copy batches of columns from a source without mapping each column
individually. For further information about dynamic schemas, see [Dynamic schema](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/dynamic-schema).

This
dynamic schema feature is designed for the purpose of retrieving unknown columns of a
table and is recommended to be used for this purpose only; it is not recommended for the
use of creating tables.

Information noteNote: If you are using the dynamic schema feature, make sure date pattern is set
for the dynamic column in the Date Pattern field in the
schema editor. The default date pattern for the dynamic column is
"dd-MM-yyyy".

Click Edit
schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

| ## Advanced settings | Properties | Description | | --- | --- | | Advanced separator | Select this check box to change the used data

An improper minimum inflation rate may result in *Zip bomb detected*
exception when you try to open an Excel file. You can eliminate exceptions of
this type by setting the minimum inflation rate to a smaller value.

to output the data separately depending on the schemas identified in the file.
You can use a Row >
Reject link to filter the data which doesn't correspond to the
type defined. For an example of how to use these two links, see [Procedure](https://help.qlik.com/talend/en-US/components/8.0/processing/textractxmlfield-tlogrow-tfileinputdelimited-tfileoutputdelimited-procedure-standard-component-drop). | | Limitation | Due to license incompatibility, one or more JARs required to use this component
