It can be corrected several times, depending on the regulations and specific conditions of the journal.
After the publication of SCI papers, if mistakes need to be corrected, the author can correct them by submitting a request for corrigendum to the editorial department of the journal. Corrigendum is an inevitable behavior to correct the mistakes in SCI papers and show readers more rigorous and correct content. But for journals or authors, it is still necessary to minimize the number of errata.
Different magazines have different requirements. If there is any problem with SCI articles after publication, the author can apply for correction in time. If not, the published articles can be withdrawn. In addition, if the error type has no influence on the whole paper, such as the wrong name of the unit and the error of individual data (which does not affect the result), it can be corrected by errata. If the wrong content has affected the whole, such as changing the results and conclusions, it must be taken back.
As for the number of errata, generally speaking, it is reasonable to make errata as long as the mistakes are corrected correctly and the readers are misled. However, it can be corrected several times, depending on the regulations and specific conditions of the journal. Some journals may have strict restrictions on this, and some may be more relaxed. Therefore, if you have any questions about this, you'd better consult directly with the editorial department of the journal where you contributed.
