Hi,
Follow the step as below, I have tried with your sample input instance and it works:
- To start with have an input instance file without the spaces in Field3 and Field8
"99103" "2" "PfghAS,Nskimavd,522" "12629" "12545" "20141001" "" "Omsetningsleiemvapl.kreditnovember2014-AskimStorhandel-NskimStorhandel"
"99103" "2" "JkifnyskAS,Amkinkimavd,522" "12629" "12545" "20141001" "" "xyzdgfjsleiemvapl.kreditAugust2014-AskimStorhandel-AmkinkimStorhandel"
Provide this as the input to the Flat-file schema wizard. Note, the above given input instance does have 3 spaces at the start of every line. i.e 3 spaces before "99103".
- Then as usual for record delimiter select {CR}{LF}. And in the Child elements page, set the first record as Repeating Record and second/others as Ignore I believe, youre already doing this.
- Then while delimiting the record:
- In Child Delimiter, select {SPACE}
- And select the check box Record has a tag identifier and in Tag: <<give two space- Just type 2 spaces>>, then you will have child elements as shown in the below image. See the sample data used in Field3 and Field8 doesnt contain spaces as
mentioned.

- Once you get the schema created:
- Give Wrap Character Type - Character
- And Wrap Character .
Now if you get space between the Field3 and Field8 elements, this schema shall work as below:
We gave input instance without spaces to wizard to make the parsing easier with the wizard, then the generated schema can be updated as mentioned to handle the schema as your requirement.

See the above image after updating the schema, Now this output instance has Field3 and Field8 with text with spaces and has 8 fields as you wanted. Following is the schema for the same.

You may need to change the namespace name, record and field names as per your requirement.
