Unable to Import LCMBIAR which Contains Publication

Hi Experts,

We are using BO 4.0 SP6. We are trying to backup our file from production server to DR server.

At first, we exported all the reports in one LCMBIAR (we have selected all the dependencies) and imported in DR but failed.

So we suspect their is an issue about the file size, therefore we tried to export folder by folder and import again in DR server. All the LCMBIAR files are successful imported except for a LCMBIAR file which contains publication.

Is there any limitation? Please advice.

Regards,

Kim Yun
