Import proposal lines in Dolibarr 18.0.2

Using my Dolibarr
1

Hi All

I am trying to import proposals to Dolibarr 18.0.2 linux server, this version has 2 files, the first for the headers and the second for the proposal lines, the first file imported without problem, but the proposal lines get this error:

Cannot add or update a child row: a foreign key constraint fails (jastechc_doli102.llxqy_propaldet, CONSTRAINT fk_propaldet_fk_propal FOREIGN KEY (fk_propal) REFERENCES llxqy_propal (rowid)).

The problem is that the fk_propal field in the example indicates that it should be the name of the proposal, but in the error it indicates that it should be the rowid.
Could you help me tell me how I should proceed?

Thanks in advance
