I have noticed that after exporting the schema from one environment and importing the same into another environment, name of the schema is starting as Upper case letter in the Export bundle and same is replicating into SPE dashboard .However in the SPE_SCHEMA table, name of the schema is inserting as a lower case. Because of this during execution of the map, ITX Advance/SPE Engine is throwing äóìcom.ibm.spe.core.schemas.InvalidSchemaException Could not find schema with name: Name of the schemaäó. It would be good, if we can maintain same case in äóìPain.001.001.03.xsdäó while exporting the schema.
For your reference below I am attaching.
1) Export schema
2) Screen shot of the SPE_SCHEMA table entry
3) Log file of ITXAdvance/SPE.
