The partially illegible Mau inscription of Sallakshana's descendant Madana-varman appears to credit him with successful campaigns in "Antarvedi vishaya". Kalhana's writings suggest that Antarvedi was a name for the land between the Ganga and the Yamuna rivers, centered around Kanyakubja (Kannauj). Because of the fragmentary nature of the inscription, different scholars have interpreted it in different ways. Alexander Cunningham believed that Sallakshana's forces merely carried out a brief raid in this region. H. C. Ray speculated that Sallakshana fought with a Kannauj Rashtrakuta prince (possibly Gopala or one of his predecessors) before aborting his campaign. S. K. Mitra theorized that he unsuccessfully tried to capture Kannauj. D. C. Ganguly, on the other hand, proposed that the Chandelas defeated the rulers of Kannauj, which was subsequently ruled by the Gahadavalas. N. S. Bose theorized that the Gahadavalas invaded the Chandela territory; the military success mentioned in the inscription was Sallakshana's repulsion of this attack. According to R. K. Dikshit, the Ghaznavids under Masud III invaded Kannauj region during the reign and defeated the Gahadavalas and their Rashtrakuta feudatories. Taking advantage of this situation, Sallakshana may have captured Antarvedi.
Sallakshana-varman is also mentioned in the Ajaygarh rock inscription of Kalyanidevi, the wife of his descendant Viravarman. According to this inscription, Sallakshana's sword "took away to the fortune of the Malavas and the Chedis. The success against the Malavas may have been a raid against the Paramara king Naravarman. The success against the Chedis (the Kalachuris of Tripuri) was probably refers to an expedition against the Kalachuri king Yashah-Karna."
An inscription of Jajalla-deva, the Kalachuri king of Ratanpur, dated to 1110s CE, states that he was "honoured like a friend" by the ruler of Jejakabhukti. F. Kielhorn identified this Jejakabhukti ruler with Sallakshana's father Kirttivarman. But V. V. Mirashi believed that this ruler was Sallakshana himself, because Jajalla appears to have imitated his copper coins.
