Is it possible to correct the documents submitted to i.EKA from the cash register in Lithuania?

The i.EKA project for fiscalization in Lithuania was launched last year. As a reminder, the fiscal devices have been upgraded with a new module, direct communication with tax authorities, and other features. The fiscal documents have also been defined with rules. Besides sales transactions, there are other transactions, such as returns, voids introduced for different situations, on-going errors, etc.

The question is: what needs to be done if there is some mistake in the document that is submitted to the I.EKA from the cash register, and how should it be corrected? Also, we can have different situations where documents submitted to i.EKA can be corrected in two ways: after joining i.EKA or by providing revised document data from the cash register.

In both cases, when correcting the data in a document that has already been created, printed, and submitted to i.EKA, in the "Reason for Correction" box, it is necessary to indicate which information in the document has been corrected and the reason why the information in the document submitted to i.EKA is incorrect.
